Description

Technical Field

[0001] This invention relates to the field of paperboard production, and more particularly to a paperboard composite slitting machine. Background Technology

[0002] In the production of cardboard, cartons, and packaging materials, it is common to laminate paper cores and face sheets, followed by slitting according to final product specifications. Traditional production methods typically involve a multi-step process: first, the paper core is glued and pressed with the face sheets on a laminating machine; then, the semi-finished roll is transferred to a separate slitting machine for cross-cutting and longitudinal cutting. This multi-equipment, multi-process production model results in long production lines and requires significant floor space. Furthermore, the transfer and reloading of semi-finished products between different machines not only increases the workload for operators but also makes the material susceptible to scratches, wrinkles, or misalignment due to tension variations or misalignment, affecting product quality and yield.

[0003] Therefore, it is necessary to make further improvements. Summary of the Invention

[0004] The purpose of this invention is to overcome the above-mentioned problems. We provide a paperboard composite slitting machine that can reduce the overall length of the production line and effectively improve production efficiency.

[0005] To achieve the above objectives, the present invention provides a paperboard laminating and slitting integrated machine, comprising a machine body, on which a first unwinding roller, a gluing mechanism, a pressing mechanism, a second unwinding roller group, and a slitting mechanism are sequentially arranged. The gluing mechanism includes an upper gluing roller and a lower gluing roller arranged vertically, forming a paper core channel between the upper and lower gluing rollers. The paper core on the first unwinding roller passes through the paper core channel, and the upper and lower gluing rollers are used to glue the upper and lower end faces of the paper core, respectively. The pressing mechanism includes an upper pressure roller and a lower pressure roller. The second unwinding roller group includes a second unwinding roller and a third unwinding roller arranged vertically. The upper paper on the second unwinding roller is guided and pressed onto the upper end face of the paper core by the upper pressure roller, and the lower paper on the third unwinding roller is guided and pressed onto the lower end face of the paper core by the lower pressure roller. The slitting mechanism includes a slitting blade group and a slitting table arranged vertically. The slitting blade group includes a cross-cutting blade module and a longitudinal cutting blade module.

[0006] In one or more embodiments, the cross-cutting module includes a gate and a hydraulic cylinder, the hydraulic cylinder being used to move the gate up and down.

[0007] In one or more embodiments, the longitudinal cutting module includes a crossbar and a plurality of longitudinal cutting blades. The longitudinal cutting blades are slidably connected to the crossbar via a blade holder. The blade holder is provided with a locking screw, which is positioned facing the crossbar.

[0008] In one or more embodiments, the machine body is provided with a glue-applying box, the bottom of the glue-applying box is provided with a glue outlet, and a glue-applying roller is rolled on the glue outlet, the glue-applying roller being in contact with the glue-applying roller.

[0009] In one or more embodiments, the machine body is provided with a lower glue box, the top of the lower glue box is provided with an opening, at least a portion of the lower glue roller is located inside the lower glue box, and a scraper is provided on one side of the machine body located on the lower glue roller.

[0010] In one or more embodiments, the end of the scraper blade abuts against the lower glue roller, the tail end of the scraper blade is rotatably connected to the machine body, and the machine body is provided with a spring member that abuts against the scraper blade. The spring member applies elastic force to the scraper blade to keep the scraper blade in contact with the lower glue roller.

[0011] In one or more embodiments, the first unwinding roller is located obliquely below the gluing mechanism, and a plurality of first guide rollers are provided on the machine body. The first guide rollers are used to guide the paper core on the first unwinding roller to the gluing mechanism.

[0012] In one or more embodiments, a second paper guide roller is provided between the pressing mechanism and the slitting mechanism of the machine body.

[0013] Compared with the prior art, the advantages of this invention are: by sequentially integrating the first unwinding roller, gluing mechanism, pressing mechanism, second unwinding roller group, and slitting mechanism into the same machine body, a fully integrated continuous production process from unwinding the paper core and face paper to lamination and slitting is achieved. This greatly shortens the production process, reduces intermediate transfer and repeated feeding of semi-finished products, significantly improves production efficiency, and the compact structural design effectively saves equipment floor space.

[0015] To enhance understanding of the present invention, the present invention will be further described in detail below with reference to embodiments and accompanying drawings. These embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0016] See appendix Figure 1-2This application provides a paperboard laminating and slitting integrated machine, which includes a machine body 1. A first unwinding roller 2, a gluing mechanism, a pressing mechanism, a second unwinding roller group, and a slitting mechanism are sequentially arranged on the machine body 1. The gluing mechanism includes an upper gluing roller 3 and a lower gluing roller 4 arranged vertically, forming a paper core channel between the upper gluing roller 3 and the lower gluing roller 4. The paper core 5 on the first unwinding roller 2 passes through the paper core channel. The upper gluing roller 3 and the lower gluing roller 4 are respectively gluing the upper and lower end surfaces of the paper core 5. The pressing mechanism includes an upper pressure roller 6 and a lower pressure roller 7. The second unwinding roller group includes a second unwinding roller 8 and a lower pressure roller 9 arranged vertically. The three unwinding rollers 9 and 8 are used to guide and press the top paper 10 on the second unwinding roller 8 onto the upper end face of the paper core 5 via the upper pressure roller 6. The bottom paper 11 on the third unwinding roller 8 is guided and pressed onto the lower end face of the paper core 5 via the lower pressure roller 7. The slitting mechanism includes a vertically arranged slitting knife group and a slitting table 12. The slitting knife group includes a cross-cutting knife module and a longitudinal cutting knife module. By sequentially integrating the first unwinding roller, gluing mechanism, pressing mechanism, second unwinding roller group, and slitting mechanism into the same machine body, a fully integrated continuous production process from unwinding the paper core and face paper to lamination and slitting is realized. This greatly shortens the production process, reduces intermediate transfer and repeated feeding of semi-finished products, significantly improves production efficiency, and the compact structural design effectively saves equipment floor space.

[0017] The cross-cutting module includes a gate 13 and a hydraulic cylinder. The hydraulic cylinder is used to drive the gate 13 to move up and down. Using the hydraulic cylinder to drive the gate for cross-cutting can provide a stable and powerful cutting force, ensuring fast and flat cutting of composite paperboard, improving cutting accuracy and efficiency. At the same time, the hydraulic transmission is smooth, which helps to reduce equipment vibration and noise.

[0018] The longitudinal slitting module includes a crossbar 14 and multiple longitudinal slitting blades 15. The longitudinal slitting blades 15 are slidably connected to the crossbar 14 via a blade holder 16. The blade holder 16 is provided with a locking screw 17, which faces the crossbar 14. The position of the longitudinal slitting blades 15 on the crossbar 14 can be flexibly adjusted and locked by the locking screw 17, so that the longitudinal cutting width can be quickly adjusted according to the product specifications, improving the adaptability and production flexibility of the equipment and meeting the slitting requirements of different sized cardboard.

[0019] The machine body 1 is provided with a glue-applying box 18, and a glue outlet is provided at the bottom of the glue-applying box 18. A glue-applying roller 19 is rolled on the glue outlet. The glue-applying roller 19 contacts the glue-applying roller 3. The glue-applying box 18 supplies glue through the glue-applying roller 19, which ensures the uniform distribution of glue on the surface of the glue-applying roller, thereby making the glue coating on the upper surface of the paper core 5 uniform, improving the composite quality and bonding strength.

[0020] The machine body 1 is provided with a glue box 20, the top of which is open. At least part of the glue roller 4 is located inside the glue box 20. A scraper blade 21 is provided on one side of the glue roller 4 on the machine body 1. Since the glue roller 4 is located inside the glue box 20, it is immersed in glue, ensuring sufficient glue supply. The scraper blade 21 can scrape off excess glue from the surface of the glue roller 4, control the glue layer thickness, avoid glue waste and dripping, and ensure that the glue is evenly applied to the lower surface of the paper core 5.

[0021] The end of the scraper blade 21 abuts against the lower glue roller 4, and the tail end of the scraper blade 21 is rotatably connected to the machine body 1. The machine body 1 is provided with a spring member 22 that abuts against the scraper blade 21. The spring member 22 applies elastic force to the scraper blade 21 to keep the scraper blade 21 in contact with the lower glue roller 4. The continuous elastic force provided by the spring member 22 ensures that the scraper blade 21 always maintains stable contact with the surface of the lower glue roller 4, which can effectively adapt to the slight jump or wear of the roller and ensure the stability of the scraping effect.

[0022] The first unwind roller 2 is located diagonally below the gluing mechanism. Several first guide rollers 23 are provided on the machine body 1. These first guide rollers 23 guide the paper core 5 on the first unwind roller 2 to the gluing mechanism. The first unwind roller 21 guides the paper core 5 through the first guide rollers 23, forming a smooth paper core transport path. This helps maintain the tension stability of the paper core 5 before entering the gluing mechanism, preventing deviation and wrinkling, and laying a good foundation for subsequent gluing and laminating processes. A second guide roller 24 is located between the pressing mechanism and the slitting mechanism on the machine body 1. The function of the second guide roller 24 is the same as that of the first guide roller 23, and will not be repeated here.
